ABSTRACT:
Reflectors for indicating, for example, the dividing line between traffic lanes and road edges include an above-the-road housing portion that has a spherical contour rising gradually from the road in all directions. Impact, resistant solid metal shoulders have between them a light channel with divergent side walls and an upwardly and outwardly sloping upper surface. Bridges across the channel, from shoulder to shoulder protect reflective lenses from tires and lift narrow two wheel vehicle tires up and over the lenses. A removable assembly retains the lenses latched in place. Wash openings directly above the lenses expose the lenses to direct impact by rain and reservoirs collect water for splash washing. Bases for the reflectors can be surface mounted, imbedded for new road construction, or anchored by bolts in a shallow recess. Extension below the road surface level of the assembly retaining the lenses permits larger reflector lenses in the housing of the reflectors imbedded and bolted in a shallow recess. A removable model has a permanently secured base below road level with a detachable upper housing locked in place by a sturdy solid metal wedge between cooperating slots and lugs on the base and housing. This locking arrangement, the lens assembly retaining provision, and specially coded bolts securing the reflectors are vandal-resistant.
